` IMPROVEMENT IN APPARATUS FOR SETTING BOXES IN CARRIAGE-HUBSQ Specification forming part of Letters Patent No. 122,295, dated December 26, 1871;'antedated December 12, 1871.

thereon, to be a full-7 clear, and exact description of the same, and which said drawing 'constitutes part of this specification and represents, in

Figure 1, a side view 5 Fig. 2, a top view; Fig.

3, a vertical central section; Fig. 4, a perspective view of the apparatus' with the head re-` moved; and in Fig. 5, the head detached.

This invention relates to a device for setting boxes in carriagehubs--that is, in the press-by means of which the boxes are forced into the hub, the `object being` to insure a central position of the hub and a vertical pressure upon the box. To this end my invention consists in the arrange ment of a hea-d through which the screw passes, combined with swinging arms attached to the base, which lock onto the head and hold it in position, or allow its removal, as the case may be, and with a central adjusting-bed for the hub.

A is the base, formed, by preference, by four arms, as seen in Figs. 2 and 4. To each of these four arms a rod, B, is pivoted, so as to swing to- Ward or from the center, their upper ends constructed in T- shape, C. D is the head through which the screw E passes, as seen in Fig. 3. The head D is constructedas seen in Fig. 5, with recesses a corresponding to the rods B, and into which the rods maybe turned, as seen in Figs. 1. and V2, the T-shaped end C rest-ing in seats in the said head. On the bed A a seat, F, is formed for the hub, provided with adjusting-screws f1 The outer end of the hub is set on the bed A, as seen in Figs. l and 3, the screws adjusting its position centrally below the pressing-screw E. Into the hub the box is placed in the usual manner, and the screw turned down thereon by means of the lever L until the` box is forced into its proper place in the hub; then the screw is withdrawn, the arms thrown back, as in Fig. 4, for the removal of the head and hub, and for the insertion of a second hub. I

By this construction a central position of the hub and of the box relative to the pressing-screw `is insured. ,p

I claim as my invention- The herein-described apparatus for setting' JOHN H. SHUMWAY. (31)
